Title: Formation of wiring
Inventor: HIBINO SATOSHI
IPC: H01L21/768
Filed: 1993-12-22
Abstract: PURPOSE:To increase the yield in the formation of wiring including a step for filling a contact hole by depositing W (tungsten) nonselectively. CONSTITUTION:After making a first contact hole of small size being filled by a deposition film of predetermined thickness in an insulation film 12 covering the surface of a substrate 10, W is deposited selectively on the substrate through TiN and then it is etched back to form a TiN film 13A and a W film 14A filling the first contact hole. After making a second contact hole larger than the first contact hole in the insulation film 12, TiN and an Al alloy are deposited sequentially on the surface of the substrate and then the deposition layers 15, 16 are patterned to form a wiring layer. Since the large contact hole is not filled with W, insufficient filling is prevented.
